Overview

Brought to you by the world’s leading aluminium frame engineers, Defy redefines the performance possibilities of an entry-level road bike. Born in Giant’s own in-house aluminium forging facility and engineered with FluidForm ALUXX SL aluminium tubes, it climbs, corners and sprints better than many bikes that cost thousands more. Frame technologies include the OverDrive steerer tube for stiffness and sharp steering and PowerCore oversized bottom bracket area for stiff, efficient power transfer.

Weight

The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All Giant bikes are designed for best-in-class weight and ride quality.
